ventilation. As the ball pressure test is not considered to be an ageing test such forced gas ventilation
is not required and should not be confused with forced convection.
For the purpose of ball pressure testing chambers with or without forced convection may be used,
provided all other requirements are fulfilled.
Following clause 5.2 of the standard and considering the note there, a separate thermocouple on or
right below the surface of the test specimen support and as close as practical to the test sample shall
be used to check that the temperature of the test specimen support does not significantly deviate from
the test temperature.
In addition measure the air temperature as close as possible to the test specimen.
In case of non-round indentation obtained, report the biggest diameter measurement observed. The
maximum difference between the longest and shortest measurement should not exceed 0,2 mm.
Where the product standard contains differing or conflicting requirements to IEC 60695-10-2 or to this
decision sheet these product standard requirements override the requirements from IEC 60695-10-2
and this decision sheet.
